CAR FOR ROUNDABO'UTS.

Application filed July 3, 1924, Serial No. 723,965, and in France July 27, 1923.

This invention relates to a car for roundabouts characterized by the use of eccentric wheels designed to produce multlple movements forming a special attraction roundabout.

for the An embodiment of the invention is shown by way of example on the accompanying drawing, in which Fig. 1 shows in side elevation a car in the preferred form of construction.

Fig. 2 shows in rear View the car shown in Fig. 1.

Figs. 3 and 4 are diagrams in plan View.

Fig. 5 shows 111 side elevation a second form of construct-ion of the car.

The characteristic features of the inventhe eccentric wheel for has two keyed on the axle eferably The two so that their eccentricity is in opposite directions.

The car, being drawn along mechanical movement, the results f opposite directions of eccentricity front wheels are 1) An ascending and descendin ment of either side of the car at ca tion of the wheels;

(2) A shifting of the by a convenient rom the of the movech rotafront end of the car in lateral direction producing a pivoting movement of the same in horizontal plane owing to the fact that the one wheel rotates with the maximum development, the other wheel turning with the minimum development and inversely. This movement or shifting in lateral direction is maximum when the radius of eccentricity of th e wheels is parallel to the ground, the axles being at this moment parallel to the ground.

This

movement of shifting in lateral direction is illustrated in the diagram which the course of movement is sup be developed in straight line.

The rear wheel (Z is keyed on its which it is also eccentrically mounte Figs. 3 and a in posed to axle on d. This axle e is mounted in two journals f, 7 which permit of and sliding in longitudinal direction.

the wheel turning around itself ing to the movement of the front axle with regard to the ground at every semi-revolution of the front wheels one sliding movement of the rear axlee in its ournals will occur, this liding movement being facilitated by the inclination of the entire carriage frame and stopped by compression springs g, g on the rear axle and designed to soften the shock.

The rear wheel. (Z being of shorter diameter than the front wheels the swinging movement from the front to the rear is different at every revolution whereby the peculiar effect produced is further increased.

In the form of construction shown in Figs. 5 and 6 the small wheel h is the front wheel and it is supported by a pivotal fork 2' maintained in position by the springs j, The pivoting tension of two movement of the car in lateral directions due to the eccentricity of the two large wheels 70, 7c, keyed on the rear axle Z, produces a cor responding inclination of the front wheel with regard to the frame, said inclination the springs j, 7'. Two stops ed to prevent, in case of springs, the total swinging fork.

The invention has for its application of the eccentric for roundabouts. cars which together form effected by any being checked by m, m are providbreakage of the or rocking of the object mainly the wheel on the cars The drawing along of the a roundabout is convenient mechanical means attached at a suitable point of each car at the centre of the axle wheels,

which carries two this point being the only point of the apparatus which has a constant position.

These arrangements of the however to do with roundabout have the lnvention.

The construction of the cars might be different from the descriptlon as stated above, always provided that the eccentric wheel be used; for instance the two wheels may fixed on their common axle so that their eccentricity is of the a very irregular raising an same direction whereby d rocking will be communicated to the car, independent of the position of the single Wheel with regard to the two fixed Wheels.

This system of eccentric Wheels could be applied also to roundabouts with bicycles.

1 claim A car for roundabouts comprising in combination a front axle, two eccentric Wheels keyed on said front axle the eccentricity of said two Wheels being of opposite directions, 10 an axle at the rear, one small eccentric Wheel mounted on said rear axle, journals in which said rear axle can slide in longitudinal direction, and springs on said rear axle for limiting and softening the lateral move- 5 ments of said rear Wheel.

ln testimony whereof I my signature.
